Immunocompromised Persons
Zoster vaccine should not be administered to persons with primary or acquired immunodeficiency including:
“On the other hand, patients with CLL should be regarded as immunodeficient as far as vaccination with live attenuated organisms is concerned and these should be avoided.”
Hamblin, D. and Hamblin, T. J. The immunodeficiency of chronic lymphocytic leukaemia British Medical Bulletin 2008; 87: 49–62 A.
Below are quotes from two CLL experts who many of my leukemia friends know too well.
“First, patients with CLL should never have live vaccines.“ Dr T. J. Hamblin, Professor of Immunohaematology Southampton 1986 to present. Honorary Consultant Haematologist Kings College Hospital, London, 2004-present.
“CLL patients should not get the shingles vaccine as it is a live virus.” Dr. Richard Furman, assistant professor, Division of Hematology and Oncology, Weill Medical College at Cornell University, New York, NY.
I will keep you posted, though the change will come slowly, it surely will come.
To quote Rabbi Tarfon
It is not your part to finish the task, yet you are not free to desist from it.

Hi Brian
Clearly there is a problem here, but perhaps it is the nature of the Zoster virus that makes it an exception to the Hamblin et al rule about no live vaccines.
Chances are you and I and about 99% of humans have been exposed to chickenpox at sometime in our childhood. This exposure could mean that we have Zoster virus in our bodies already. While the virus we have is still 'alive' it is in a latent state living in nerve ganglia cells.
It is this latent virus that causes shingles. You can NOT get shingles from the live vaccine. It must be contracted as chickenpox (varicella zoster virus) and then go through years of latency before it can become reactivated as shingles.
What triggers this reactivation is immune system deficiency or perhaps psychological stress.
Since the vaccine can not 'give' a patient shingles it could add a load to the immune system. The effects on CLL patients of the Zoster vaccine is virtually unknown.
In this case I think caution is advised as the CLL experts point out, until a clinical study can resolve this.
